Title:

DUAL OPTICAL FREQUENCY COMB GENERATING OPTICAL SYSTEM, LASER DEVICE AND MEASUREMENT DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/073701

Kind Code:

A1

Abstract:

This dual optical frequency comb generating optical system comprises: an amplification unit for emitting laser amplification light in the circumferential direction of a first optical fiber loop and in the reverse-oriented direction along the circumferential direction; and a laser amplification light returning unit for emitting the laser amplification light to the first optical fiber loop only when a predetermined condition is satisfied by the phase difference between the laser amplification light that has been wave-guided along the circumferential direction and the laser amplification light that has been wave-guided along the reverse-oriented direction.
